Ambient Air Temperature Sensor for 1991-2005 Buick LeSabre & More - Walker 210-1035

Walker Products Ambient Air Temperature Sensors are OE Replacement components that deliver accurate outdoor air data for HVAC and temperature display systems.

• Walker Products Ambient Air Temperature Sensors are OE Replacement components engineered to deliver precise temperature readings of the outside air. This data is critical for vehicles equipped with automatic climate control, temperature display, and other ambient-dependent functions such as engine idle speed and HVAC blend door operation. Each sensor is manufactured using high-quality thermistors and sealed housings that ensure accurate resistance values and signal output across a broad temperature range. These sensors are built for harsh environments and are resistant to road salt, moisture, vibration, and extreme heat or cold. Designed for an exact OE fit, Walker Ambient Air Temperature Sensors install quickly using factory mounting points and connect directly to the vehicle’s wiring harness with OE-matched terminals. By restoring accurate ambient readings, these sensors help maintain HVAC efficiency, prevent incorrect cabin temperature regulation, and ensure consistent system performance across all driving conditions.
• Accurate Outside Temperature Monitoring:Continuously measures ambient air temperature to support automatic HVAC control and external temperature displays.
• Supports Climate Control Accuracy:Helps the vehicle maintain consistent interior comfort and enhances HVAC efficiency in varying external conditions.
• Weather-Resistant Construction:Engineered with sealed housings and durable thermistors to resist moisture, road debris, and temperature extremes.
• OE Replacement Design:Built to match OE sensor calibration, output range, and response characteristics for reliable system integration.
• Exact OE Fit:Designed for 100% OE fitment with factory-style connectors and mounting locations for quick, plug-in installation.
